It starts with Jean inserting herself under his arm, and resting her head on his grizzled chest. This is called Minging. Then she turns on her side and he hugs her bottom. Then they roll over and she hugs his. It's like toast, you have to do both sides. The climax is the Smumph. He rolls one leg over her and sinks as if she were pillows.
John is convinced being that being snuggled regularly gives people an aura. He is sure the old gent opposite is snuggled. So is the laughing girl at the end of the row. Not many other people are, and he feels sorry for them.
He is sure that snuggled people have a broader perspective on life. He could write a book about it: The Secret of Snuggles. It would advise long warm showers afterwards as part of the general cosiness, and give practical advice on what to if someone farts. (Basically, you ignore it or light a match).
What a lucky man you are, he thinks.
